1. Properties
1.1 Physical Properties
       Physical properties have to do with the  Black Pond Liner in an as-manufactured and/or as-received state. They
are important for specifications, confirmation evaluation, and, in many cases, design. The main properites are as
follows:

 Thickness (smooth sheet, textured, asperity height)

 Density

 Melt flow index

 mass per unit area (weight)

 Vapor transmission (water and solvent)
1.2 Mechanical Properties
      There are a number of mechanical tests that have been developed to determine the strength of polymeric sheet materials. Many have been adopted for use in evaluating Black Pond Liner . They represent both quality control
and design, i.e., index versus performance tests.

 tensile strength and elongation (index, wide width, axi-symmetric, and seams)

 tear resistance

 impact resistance

 puncture resistance

 interface shear strength

 anchorage strength

 stress cracking (constant load and single point)
1.3 Endurance Properties
     Any phenomenon that causes polymeric chain scission, bond breaking, additive depletion, or extraction within
the  Black Pond Liner must be considered as compromising to its long-term performance. There are a number of
potential concerns in this regard. While each is material-specific, the general behavior trend is to cause the geomembrane
to become brittle in its stress-strain behavior over time. There are several mechanical properties to track in monitoring
such long term degradation: the decrease in elongation at failure, the increase in modulus of elasticity, the increase
(then decrease) in stress at failure (i.e., strength), and the general loss of ductility. Obviously, many of the physical
and mechanical properties could be used to monitor the polymeric degradation process.

 ultraviolet light exposure (laboratory of field)

 radioactive degradation

 biological degradation (animals, fungi or bacteria)

 chemical degradation

 thermal behavior (hot or cold)

 oxidative degradation
